12 ounces cream cheese at room temperature (1 1/2 packages)

Instructions
Cupcakes:
Preheat to 350A degrees F.
Fill 2 cupcake pans with paper liners.
Whisk first 4 ingredients in medium bowl to blend.
Using electric mixer, beat sugar and butter in large bowl until well blended.
Beat in eggs 1 at a time, beating well after each addition.
Beat in yolk.
Add cocoa and beat until well blended.
Add flour mixture in 3 additions alternately with ice water in 2 additions, beginning and ending with flour mixture and beating until just blended and smooth after each addition.
Fill cupcake liners 1/2 full with batter.
I like to use a large cookie scoop for this, but a spoon will work too.
Bake cupcakes until tester inserted into center comes out clean, about 20-25 minutes.
Cool cupcakes in pans on racks 15 minutes.
Can be made 1 day ahead.
Store in cupcake storage containers.
Frost with desired frosting.
Cream Cheese Frosting:
In bowl for mixer, combine butter and cream cheese and medium speed until well blended and smooth.
Add vanilla, mix until incorporated.
Slowly add powdered sugar and with mixer on med-high blend until creamy and desired consistency.
